I recently noticed a purple bump on the skin above my penis. It just appeared there one day and I thought it would go away but it didn't. It was irritating me when ever I touched it so I decided to squeeze it. It felt like it was going to pop but never did so I left it. It started getting bigger so I tried again and this time it did pop but dark red blood came out and so did some pus. I would t stop bleeding for about an hour. It hurt after I popped it and it still does. I am very scared of what this might be but I'm to embarrassed to see a doctor considering the location. Does anyone know what this is?
